Jimmy Fallon, The Roots and Sesame Street perform the ‘Sesame Street’ theme song

Jimmy, Questlove, The Roots and the Sesame Street characters performed the entire “Sesame Street” theme song using nothing but classroom instruments like tiny xylophones and recorders and kazoos.

I don’t think there’s anyone on TV that looks like they’re having more fun than Jimmy Fallon does. It’s going to be really interested to see how much, if any, he changes it up when he takes over hosting “The Tonight Show” in 2014.
